only i have never have good experience with using extensions when updating my forums

You will have even more bad experiences updating your boards if you start changing core code in preference to using extensions

You don't need a extension for this.
Just setup a group avatar and it is OK.
(Manage groups)

ok, I'll bite, what group are you going to use for this? you can't use the guest group because if someone is registered then they would not be in the guest group. you can't use the registered usergroup because they either will or won't choose an avatar.

I think maybe you are thinking about something other than what the OP asked for.
